# Effect from hyperbolic law in periodic table of elements.

Hyperbola curves Y = K/X and Y =(mx + n)/(px + q) at determination of the upper limit of the Periodic System have been studied. Their interdependence is shown by the example of mathematical calculations in chemistry.

1 Introduction. Mathematical basis

Our previous article shows that the Y content of any element K in a chemical compound is decreasing in case molecular mass X is increasing in the range from 1 up to any desired value in compliance with rectangular hyperbole law Y = K/X. Simultaneously, fraction (1-Y) is increasing in inverse proportion in compliance with formula 1 - Y = K/X or

Y = X - K / X. (1)

It is known that the function

y = ax + b / cx + d (2)

is called a linear-fractional function [2]. If c = 0 and d 6 [not equal to] 0, then we get linear dependence y = a/d x + b/d. If c [not equal to] = 0, then

[MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII.]. (3)

Supposing that X = x + d/c , bc-ad/[c.sup.2] = k [not equal to] = 0, Y = y - a/c, we get Y = K/X , i.e. rectangular hyperbole formula which center is shifted from coordinates origin to point C (-d/c ; a/c).

As we can see, formula (1) is a special case of the function (2), cause coefficient d = 0. Then, determinant D(ad - bc) degenerates into -bc. There exists a rule: when D < 0, (K >0), real axis together with X axis (abscissa axis) makes an angle +45[degrees]; and if D > 0, then the angle is -45[degrees]. In our case D = a x 0 - (-K) x 1 = K. Therefore, real axis, on which tops of all new hyperboles will be located, shall be in perpendicular position to the axis y = k/x. At that, the center is shifted from the coordinates origin C (0; 0) to the point C (0; 1). That means, in our case, semi-axes

a = b = [square root of 2|D| / [c.sup.2]] = [square root of 2K]. (4)

Then the coordinates of the top of the other hyperbole Beryllium will be: [X.sub.0] = [Y.sub.0] = [square root of K] = [square root of 9.0122] = 3.00203 and X' = 60.9097, Y' = 1-Y = 1 - 0.14796 = 0.85204.

In order to avoid possible mistakes let us use the following terminology: hyperbole of y = k/x kind is called straight, and linear-fractional--an adjoining one.

Figure 1 demonstrates these curves which represent five elements from different groups: chlorine (No. 17), zirconium (No. 40), wolfram (No. 74), mendelevium (No. 101), and the last one (No. 155). Peculiarity of the diagrams is symmetry axis at content of elements equal to 0.5. It is clear that both hyperboles of the last element and ordinate axis limit the existence area of all chemical compounds related to one gram-atom.

[FIGURE 1 OMITTED]

Previously [1], we proved that all the elements of Periodic System can be described by means of rectangular hyperbole formulas. That is why, it is quite enough to present several diagrams in order to illustrate this or that dependence. The same is valid for linear-fractional functions which curves are directed bottom-up. If we put the picture up by symmetry axis, we shall see that they fully coincide with straight hyperboles. At the cross point of straight and adjoining hyperboles on this line, abscissa is equal to doubled atomic mass of the element. Coordinates of another cross points for each pair of hyperboles have the following parameters: X is equal to the sum of atomic mass of two elements ([K.sub.1] + [K.sub.2]), and Y has two values [K.sub.1]/[K.sub.1] + [K.sub.2] and [K.sub.2] / [K.sub.1] + [K.sub.2]. Mentioned above is valid up to the upper bound of Periodic System inclusive.

As we can see on Figure 2, (A00) and (B01) are real axes of straight and adjoining hyperboles accordingly; and, AC and BD, (00E) and (01E) are tangents to them. Real axes are perpendicular to each other and to tangents. And all of them are equal to each other. Diagonals (00D) and (01C) divide straights AE and BE in halves.

[FIGURE 2 OMITTED]

There are formulas of mentioned lines. Cross points of these lines are also calculated. Abscissa of cross sections are values divisible by atomic mass of the last element: 0; 205.83; 274.44; 329.328; 411.66; 548.88; 617.49; 823.32 (0; 0.5; 0.667; 0.8; 1.0; 1.333; 1.5; 2.0).

For reference, Figure 3 demonstrates graphical construction for tungsten.

[FIGURE 3 OMITTED]

We can see, that knowing real axes (normal to the top of hyperboles), it is very easy to build up tangents to any element, if required, in order to check accuracy of chosen tops. For that, it is necessary to calculate formula of the straight which passes through the point M1 (x1; y1) and parallel y = ax + b:

y - [y.sub.1] = a(x - [x.sub.1]). (5)

2 Application of law of hyperboles for chemical compounds

As it has already been mentioned above, the law is based on the following: the content of the element we are determining in the substance should be referred to its gram-atom. It was shown in detail by the example of oxygen. In compliance with the formula y = k/x element is a numerator, and any compound is a denominator. For example, in order to determine content of sodium (Na) in compounds with molecular mass NaOH (39.9967), [Na.sub.2]C[O.sub.3] (105.9872), [Na.sub.3]P[O.sub.4] (163.941), NaCl (58.443), [Na.sub.2]S[O.sub.4] (142.0406) it is necessary, before the formula, to put coefficients, reducing amount of sodium in it to a unit: 1, 1/2, 1/3, 1, 1/2, accordingly. Then, numerically, part of element (Y) will be: 0.5748, 0.4338, 0.4207, 0.3934, and 0.3237. I.e. it is in one range with decreasing, and value (1-Y) with increasing. Both these curves (in pairs) which are built based on these data are referred to one element.

Method of rectangular hyperboles is worked out in order to determine the last element of the Periodic System of D. I. Mendeleev. But its capabilities are much bigger.

Let us build straight and adjoining hyperboles for sodium, chlorine and also for groups C[O.sub.3] and S[O.sub.4], which form, accordingly, carbonates and sulphates. As we can see in formula y = k/x they replace elements in a numerator. In our last work, we said that hyperboles can by formed by any numbers within location of their tops on a real axis. However, there is a rule for groups, similar to that of 1 gramatom of the element: their quantity in calculated compounds should not exceed a unit. Otherwise we get a situation shown on Figure 4.

[FIGURE 4 OMITTED]

As we can see, it is necessary to put coefficient 1/2 before the formula of hydroxide at bivalent barium. Then, his compounds will be on hyperboles. In case of non-observance of this rule, their points will be on broken line (circle).

Now we can start to solve a problem of building up new hyperboles, based on existing ones (Figure 5).

[FIGURE 5 OMITTED]

Let's mark on them several general points related to the known compounds. On sodium curves there are two points (on each curve) 1/2 [Na.sub.2]C[O.sub.3] and 1/2 [Na.sub.2]S[O.sub.4], which are also located on respective hyperboles but without the coefficient 1/2 ([Na.sub.2]C[O.sub.3] and [Na.sub.2]S[O.sub.4]). Thus, the point 1/2 [Na.sub.2]S[O.sub.4], located on the straight hyperbole of sodium, and its cross points with hyperboles C[O.sub.3] and S[O.sub.4] form imaginary broken line located between chlorine and C[O.sub.3].

In a similar manner it works with adjoining hyperboles. Let's build a formula (by three points) Y = 63.257 X - 1.0658 of a power function (or ln y = 4.1472 - 1.0658 ln x). With the help of mentioned formula we will find some more coordinates, including (obligatory) their crossing center (93.85; 0.5). Then we divide the abscissa of this point by 2 (straight and adjoining hyperboles cross at doubled value of atomic mass) we get X, equal to 46.925, and that is a numerator in a formula of new hyperboles (y = 46.925/x).

3 Conclusion

Method of rectangular hyperboles makes it possible to do the following:

* to create mathematical basis for using hyperboles of the kind y = 1 - k/x in chemistry;

* to determine existence area of the chemical compounds;

* to calculate formulas of the main lines and cross points of all the hyperboles, including the last element;

* to show the possibility of building up hyperboles whose numerator is a group of elements, including the rule of 1 gram-atom (in this case it is 1 gram-mole);

* to calculate and to build unknown in advance hyperboles by several data of known chemical compounds located on respective curves;

* to control (with high accuracy) the content of synthesized substances;

* to design chemical compounds.

Due to the fact that it is inconvenient to call each time the element 155 (that we calculated in this paper) "the last element" and by the right of the discoverer we decided to call it KHAZANIUM (Kh).
